My wife is petite (4'11") and always struggled to find clothes that fit her. She dresses conservatively because we're Muslim but she doesn't really like wearing the long gowns that many Muslim women wear, so she wears jeans and long sleeved shirts.

Anuway, she always struggled to find clothes that fit her well because she's small. Her uncle had to tailor a lot of her clothes growing up. A while back she found a fashion-as-a-service called Short Story, which markets itself for petite women; it basically sends her clothes every X-months and she tries them on and send back the ones she doesn't like or fit, tells her stylist why she is sending them back, and pays for the ones she keeps. Every time she keeps something from them she donates something from her wardrobe (net zero is the goal). And she looks great in them! They're fashionable (to the degree that my dev opinion on fashion matters), modest, and most importantly they fit her well.

Disclosure: I interviewed with Short Story last year as a consulting role but it didn't pan out.
